(3, 3, 3, 1, 64)

>?pool does say it supports up to dims=5 for float64, float32

dropping the fourth dimension and running pool(w) gives a different but possibly related error, lib not defined

Ah, KnetArrays with dims = 4 or 5 are supported, try

w2 = KnetArrays(w);
pool(w2);

Doesn’t work locally for lack of a discrete gpu

thank you, i have solved it. The tutor helps a lot.
